IMPROVEMENT IN coRN-SHELLER'S.

Specification forming part of Letters Patent No. 123,676, dated February13, 1872.

To whom t may concern:

Beit known that I, J AsoN R. GADWELL, of Onondaga, in the county ofIngham and State Vof Michigan, have invented a new and usefulImprovement in Oorn-Shellers; and I do de clare that the` following is atrue and accurate,

' The nature of this invention relates to animprovement in theconstruction of machines for shelling corn, whereby the operation of thesheller is rendered more effective and certain; and it consists in thenovel and peculiar con struction and arrangement of its several parts,as more fully hereinafter set forth.

In the drawing, A represents the framework of the machine, inclosed by asuitable casing and provided with a cover, B, in which there is adiagonal slot, a, Fig. 2, for the introduction of the ears of corn. O isa short driving-shaft, journaled in brackets D within the casing,through which one end projects to receive a crank, C. E is a spur-gear,secured Von the shaft C, and meshes with a pinion, F,

on a second shaft, Gf, which carries the conical sheller H, which isarmed with short studs spirally disposed about it., I is `an abutment,

rigidly secured to the frame-work, reaching across the interior parallelwith and so near the edgeoffthe sheller that the smallest cob will notpass down between them. The abutment is inclined from the base of thecone toward the apex of the sheller, to facilitate the discharge of thecobs through a hole in the casing at the lower ed of the abutment. J isa shield, pivoted` at its upper corners to the upper part of the casing,its lower edge resting against the outer side of the abutment, which isarmed with a series of projecting pins, c, the shield havingcorresponding slots, b, through which said pins pass, allowing theshield to lie flat against the abutment, against which it is pressed bya spring, K.

Motion being communicated .to the sheller through the crank and gearing,and the cobs fed in at the top, they fall on the sheller at its upperand larger end, whence they are carried down in the rotation of thesheller to the abutment, which holds or prevents them from passingfurther, but allows them to roll while the studs on the shelling-conetear off the grains, y l

which fall through and are discharged by the apron L below. While theear of corn is being stripped of its grain it passes along down theabutment toward the discharge, but not without being acted upon by theshelling-studs as long as there is a grain adhering to it, for thereason that the arrangement of the studs on the cone is such that agiven stud does not become tangent to and release it until the followingone of the next row engages with it, thus insuring perfection in theshelling process.

The yielding shield accommodates itself to the varying sizes of ears,andthe pins with which it is provided prevent, in the case of a verylarge one, its passing down behind or lodging between the abutment andits shield.

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination of the conical sheller H, rotated by proper means, theabutment I, provided with pins c, the hinged shield J, provided withslots b, and the spring K, the several parts being' constructed,arranged, and operated substantially as described and shown, for

` the purposes set forth.
